This was my second time to the track with this car. 295/35/18 bfg drag radial tires at 20psi.

How much faster can it go?

high impact

Do you have 853 or 241 heads? Comparing the DA, 60 foot time and mph in my opinion you definitely have a few more tenths in this combo. Improve your 60 foot and you will et a little better.

would only hook launching from idle, Every time I would try and stall it up is would only cut a 1.9 or worse 60ft.

since you dropped your car 2' do you have any other suspension components like adjustable torque arm, adjustable panhard bar or lower control arm to set your rear suspenion up? this is probably the cause or your spinning issue. the whole geometery of your rear is out of wack

I'm wondering if that lowering kit is reducing weight transfer to the rear. Might be part of your traction issue.

118 mph trap? Stock heads? NICE! Making decent power.

yep, time for rear suspension. Lca's, relocation brackets and adjustable arm. Set pinion angle to -2 degrees. Where are your shocks set? Ditch the front sway bar, loosen the front shocks and tighten the rear to 50-70% (6-8 clicks). You will have to play with settings a little but don't do too much at one time like I usually do - change one thing at a time. ;-) Get that thing hooking and you have a few more tenths in it. Then spray it and go mid tens! ;-)

3600# with me in it.

was running 15psi, is that a good pressure to run?

Damn dude! Your latest slip looks identical to mine in these type conditions (our humidity was 95% though) and I have ported dart heads. Strong running car you have there.

Nice I had a SI LS1 with full exhaust/SS4000/273 gear/DR/HP tuners runniing 1.59-1.61 7.51-7.53@90 an 11.91-11.93@112. I think you can do a little better in 60ft. You leaving of Idle and flashing the converter or you stalling it up.. I noticed my best times was from flashing the converter..

021le

Only hooks leaving off idle and flooring it.

Every time I try and stall it breaks em loose. 1.9-2.1+
